STOPQMOTION ACTUATOR.

Application led December 18. 1922. ySerial No. $07,693;

To LN wim/ifi# wmy/ #onf/rn it known that we. Gauner, UnLLerrn and lroifrzox limoni. citizens ot the United States. residing at Lewiston. in the county oi ndroscogiin and State oi'llaine. have invented certain new and useful improvements in Stop-llotion Actuators: and We do declare the 'following to be a full, clear, and exact description ot the invention, such as will enable others skilled in the art to which it appertains to malte and use the. saine. Uur invention relates to improvements in automatic stop motions for looms and relates more particularly to an attachment designed primarily Jtor the ("wmptondnowles automatic box loom. tor the purpose of bringing' the usual stop motion into play in case a shuttle should become lodged in the shuttle boX. 1

When changing bobbins on an automatic loom, it frequently happens that the bobbin does not take the correct position in the shuttle. with the result that this shuttle is trapped partly in and partly out oi the shuttle box. This leaves the binderl open and renders the protection rod inoperative and thus the loom continues to run and the other shuttle coming from the opposite end. oi the loom. will strike the trapped shuttle andv break out the Warp. also frequently breaking the .filling battery or other parts ot thevloom. it is the object of our invention however to provide an extremely simple and inexpensive, yet a highly efiicient and reliable attachment whereby Y upon a movable stop motion operating de` vice mounted on the-,breast beam for the purpose oi' engaging; it with a part of the stop motion mechanism, bringingthe loom to an immediato standstill, novelprovision being made for automatically disengaging said stop motion operating' device 'from the stop motion part operated thereby, when the proper Work has been performed, thereby preventing possible injury to parts' which might otherwise occur on complet-ion of the lays movement toward the breast beam.

llith the foregoing in view` the invention resides in the novel subject matter herein- 'after described and claimed, the. description being; supplemented by the accompanying drawmus.

Figure 5 is a vertical transverse sectional view as indicated by line 5-5 of Fig. 4. l

Figures 6 and 7 are side elevations show# ingr, different. positions ot parts.

The invention has been illustrated in connection with a loom l including the usual breast beam B. lay L, shuttle box Slshuttlc S, picker P, shipper lever'SL, and stop 'motion lever SM for releasing said shipper lever.' lVe mount our stop motion operating is an enlarged elevation oi the device upon one end of the breast beam yand it is operated by movement of the lay towardtl'iis beam in case a shuttle becomes lodged from any cause. as indicated iii-Fig. l, but means are provided for automatically dis-I engaging; said 'device fromthe stop motion lever as soon as the latter is operated.

The numeral l designatesl a support hav-l ingsT a horizontal base flange 2 and an upstanding vertical flange 3, the base 2 being.

adapted to be secured bybolts or the like 3 to the breast beam for which purpose it' is formed with slots 4. The flange. 3 is located on n line. running in the saine. direction as that in'which the lay L moves and a movable carrier is mounted upon this lange,

the carrier beingr here shown in the form of `a l'iorizontal slidably mounted bar 5 which contacts with the outer side of the Aflange 3 and is formed with longitudinal slots 6 receiviner vbolts` or the like 7 which extcndt'fult-y unrdly from this flange. Any suitable vmeans are provided for moving the carrier 5 normally toward the lay L and for this purpose,

we have shown an apertured lug 8 extendj ing Jfrom said carrier andreceiving ahori- ,zontal rod 9 in its aperture, said rod extending froman appropriate post .l0 which pro'- jects laterally from the flange 3. A coiled spring Vll surrounds the rod 9 and acts against the lug 8. an appropriateadjustable collar 12 being provided on said rod, against which the spring reacts. One end of the carriera is preferably oiset as indicated at 13 and is provided with an appropriatev shoe 14 adapted tobe struck by a lodged. shuttle as indicated in Figi, when the lay moves toward the breast beam.' f

stop motion operatingmember is carlll riedby the carrier 5 for engagement with the stop motion lever SM when said carrier is moved in the manner above set forth. This member is by preference in the form of ahorizontal arm 15 pivoted at 16 to the carrier 5 adjacent its offset end 13. The manner in Which the arni 15 acts against the lever SM is disclosed in Fig. 6, but as soon as this lever has been actuated to release l the' shipper lever SL. upon partial movement of the lay toward the breast beam, permitting the latter to move to an operative positioiuthe arm is disengaged from the. lever Sill automatically. as seen in Fig. 7, as the lay completes its movement. This prevents possible injury from resulting to any parts of the loom or attachment. which would occur if the device Werey permitted to establish a rigid connection between the lay and the lever SM, before the lay had conipleted its movement toward the breast beam. For the purpose of effecting the automatic release of the arm 15, We have shown a cam 17 adjustably secured by a suitable bolt and slot connection 18 to the base ange'Q of the support 1. rlhis cani is co-operable with an inclined shoulder 19 at one end of a recess 20 which is `cut in the vlower edge of the desired manner, it is advisable that the pivot 16 thereof shall be rather loose. Movement of said arms away from the Harige 3 however is prevented by a suitable guide finger 21 which may well be held in place by the bolt of the connection 18.

By employing the construction shown or a substantial equivalent thereof. an: attachment is provided which is simple and inexpensive. may be easily attached to a loom, and will be very effective for bringing the machine to a standstill in case the shuttle should become lodged from any cause. thereby e'ectively preventing break-outs with their consequent trouble and loss of time.

Excellent results have been obtained from a device constructed iii accordance with the present disclosure and ive theretoreconsider this construction as preferable. It is tobe understood however that within the scope of the inventionas claimed. numerous minor changes may be made.
